Unfortunately I don't have a garage at my current house, so I'll be having to park the GR Corolla outdoors.
Anyone else on here doing the same?
I'm thinking of buying a car shelter which will help keep the snow off in the winter and the dust and dirt off in the summer. They are extremely popular in the province of Quebec.
I really dislike washing my car, detailing it and then the next day it rains and it looks like crap again.
That's one reason I'm hoping to get the Circuit Edition in the silver-grey colour, it hides the dirt very well.
I have a Volkswagen SportWagen diesel for the winter, so I won't be driving the Corolla in the winter time, getting salt all over it, unless it's nice out.

I have a car cover due to the hail here.
Car shelter or carport sort of thing would be nice, but I'd be afraid they'd fall over or taken up by a tornado.

Has anyone else noticed that the GR Corolla comes in the very same colors as the GR Yaris, and that both cars are being built at the same specialized car manufacturing plant in Japan?
It wouldn't surprise me at all if the GR Corolla colors are identical to the GR Yaris.
I'm hoping Toyota offers the pearlescent white that's on the Yaris, instead of plain old standard white.
Definitely not interested in black, way too much work to keep clean, plus really shows the scratches and swirls.
My first choice would be the Heavy-metal, then either white or red.
What colors are you guys thinking of?

Why it's good news that the engine will have both port and direct injection is because most modern cars today have direct injection only, which causes lots of carbon buildup on the underside of the valves, causing performance issues.
With port injection that should eliminate a lot of this carbon buildup.

Not true about "most modern cars today have direct injection only".
While I'm not sure about other manufacturers, Toyotas in the U.S. today that use direct injection at all, will have both port & direct injection.
They already learned this carbon buildup lesson 10+ years ago.

In a core I'll take white or black, no real preference between the two. Don't really like the red, too dark and ruby for a hot hatch.

Of course I am hunting a heavy metal circuit pack, along with everyone else, their mother, and their girlfriends. But I would absolutely love a circuit pack in white as well, I think the Yaris looks best in white and so might the corolla. Would take black or white on a core.

The white is plain white, the classic Toyota Super White II. The red i think might be different.

Thank goodness. My FoST is DI only. I just cleaned the valves last weekend. Such a huge PITA.

The 4GR in the IS250 was direct injection only.

It's a Toyota, of course it'll have D4-S. The GRY gets it so it's not really "news" per se

Having port injectors also makes it easier to upgrade the fuel system

Yeah that's my point... the last 4GR IS250 was like 7 years ago, I believe 2015 model year.
D-4S (port/direct injection) has been around for a while now and most, if not all, Toyotas today have it.
Since 2013 - FR-S/86
Since 2016 - Tacoma
Since 2017 - Highlander
Since 2017 - Sienna
Since 2018 - Camry
Since 2019 - Avalon
Since 2019 - Corolla Hatch

there's more but you get the gist.

I realize those are all D4-S. I was just making a statement that Toyota did, once, make a DI only engine. That launched in 2006ish and was a lesson learned in multiple ways (DI only has reliability problems, buyers don't want a thirsty V6 that only makes 200hp).

Toyota's been doing this for a while and I'm pretty sure they were the first to switch to this system.
Most of the new engines actually come with both direct and port injection. Ford and Hyundai are good examples, but that only applies to their newly developed cars.
Toyota even put D4S on FA20 (and now FA24) so they've made it pretty clear that they don't like using DI system.
Of course there's the new "Supra" but we all know why it can't come with D4-S.
